Aussa

Aussa was a Muslim polity in the Afar lowlands of the Horn of Africa. In 1577 Muhammad Gasa moved his seat from Harar to Aussa, establishing an imamate after Adal's division; Harar broke away in 1647.

In 1734 the Afar leader Data Kadafo established the Mudaito dynasty in Aussa. His successors ruled a sultanate whose primacy other Afar rulers nominally acknowledged. Sultan Hanfadhe Aydahis consolidated Mudaito control with victory at Darma in 1834.
